Manual fixes:
* mozurl/cbindgen.toml (including headers earlier)
* NetlinkService.h (forward-declaring a necessary struct)
* nsIWebSocketChannel.idl (forward-declaring OriginAttributes).
* nsAsyncRedirectVerifyHelper.h (forward-declaring nsIEventTarget)
* CapsuleEncoder.h gets a missing Capsule forward-decl.
* WebSocketConnectionBase.h gets some missing includes.
* HappyEyeballsConnectionAttempt gets some missing includes.
* nsUDPSocket missed nsSocketTransportService2.h for OnSocketThread().
* HttpInfo missed a forward declaration.
* MockHttpAuth missed an nsCOMPtr include.
* nsHttpAuthManager missed a forward declaration for nsIHttpAuthCache.
* WebTransportSessionProxy was using mozilla::Mutex in a member without
including it.
* win32 fixes to keep include order because windows headers suck.
* nsInputStreamPump needs an Atomics.h include.

// table. With NVS, a response can declare that certain query parameters do
|
|
// not affect the response (e.g. "No-Vary-Search: params=(\"utm_source\")"),
|
|
// meaning /page?q=hello&utm_source=email should hit the same cache entry as
|
|
// /page?q=hello. An exact-key lookup misses in this case, so we need a way
|
|
// to find candidate entries that share the same base path.
|
|
//
|
|
// This index maps scheme://host:port/path (no query string) to the list of
|
|
// full entry keys — the cache storage keys used to look up CacheEntry
|
|
// objects in this table — for all entries that carry NVS metadata. On an
|
|
// exact-key miss, AddStorageEntry() consults this index to find candidates
|
|
// and checks each one for URL equivalence under its stored NVS header.
|
|
//
|
|
// A "full entry key" is the string passed to CacheEntry::HashingKey(), of

// the form "https://example.com/page?q=hello", uniquely identifying the
|

// cached response within this CacheEntryTable.
